He flicked the black talisman into the air, turning it into a thick book, turning the pages quickly.

"This is the magic weapon of our Tantra Sect, the treasure of Tantra, omniscient, omniscient, you can ask it any questions, and it can answer any questions that have answers. ”

It turned out to be this treasure and not the other sword.

"Really? You can ask anything?"

"Just ask. The man said generously.

Nangong Douling stared at the book for a while, and sighed in her heart that it was so amazing, she asked: "Hello Secret Words, I want to ask, which economist said the phrase 'there is no free lunch in the world'?"

"It was proposed by Professor 'Milton Friedman' at the University of Chicago in the United States. ”

"You really know! Then let me ask you, what is the biggest feature of the Mamenxi dragon among the dinosaurs?"

"The neck is particularly long, and the neck ribs can reach more than twelve meters. ”

"Amazing, you know this kind of cold knowledge! Then let me ask you again, there are three kinds of animals on a farm, chickens, ducks and rabbits, and their total number of feet is fifty-four, of which the rabbit's feet are three-quarters times that of chickens and ducks......"

"Ahem. The rest mage looked at her indifferently from the side.

Nangong Douling laughed embarrassedly, "I'm sorry, I'm sorry, I'm addicted to playing with such an interesting treasure, if only our Soul Attracting Sect also had such a learned magic weapon." ”

Nangong Douling finally became serious, "Baojian, Baojian, may I ask, what is under the whirlpool of the reservoir?"

The pages of Baojian's book were flipped and turned, presumably searching for answers, and each page of the book was white and there was no writing on it.

After a few seconds, the pages suddenly stopped, and Bao Jian spoke: "This direction is the extreme north of Qingcheng, where the yin qi of the entire city gathers, and before the reservoir was established, this was a barren mountain, and the bottom of the mountain led directly to the River Styx. ”

"The River Styx, are you talking about the River Styx that carries tens of millions of powerful ghosts in hell?" Nangong Douling asked rhetorically.

"Exactly, the River Styx from the first layer of hell, in the shape of a whirlpool, runs through to the eighteenth layer of hell, the River Styx was originally used as a passage to transport those ghosts who cannot be reincarnated to the various levels of hell, close to the ground, the River Styx is close to clear, there are fewer ghosts, and the ordinary river water in the world is no different, people dig mountains and mines, digging deeper, it is easy to expose the River Styx to the surface, once the water of the River Styx rushes out of the surface, it will be out of control, and it will gush out endlessly, forming floods and washing away village houses, this kind of thing happened frequently in the past. ”

The Secret Treasure goes on to state the cause and effect: " During the Northern Song Dynasty, wars were frequent, the capital Kaifeng fell, Emperor Zhenzong of the Song Dynasty temporarily moved to Qingcheng to build the capital, at that time there was a mage who had no door and no faction, in the form of divination, calculated that the Styx was too close to the emperor's bedroom, in case of the ill-intentioned enemy army scuttling through the surface, causing flooding, murdering the emperor, the consequences were unimaginable, the mage went to the deep mountains to capture the spirit beast Tianlong, suppressed above the Styx, as a guardian saint, even if the ground due to natural disasters or man-made deep cracks, as long as there is a guardian spirit, the Styx water will not rush out wantonly。 ”

"I see. "Nangong Douling had expected it to be related to Tianlong, because her master Chen Xuansheng had specially warned her three days ago that as soon as Tianlong died, Qingcheng would cause a catastrophe, but she didn't expect that it would be a flood caused by the River Styx. Bao Jian also said: "Later, the mountain was razed to the ground, the establishment of the reservoir, although the dragon was trapped in the sewer near the reservoir sleeping, but it still has mana, loyal to protect Qingcheng, this year's lunar calendar on the 29th day of the fifth month, the soul school mage Nangong Douling personally on the roof of the teaching building of Fufang Junior High School with 'nightmare spell' to kill the guardian god Tianlong, the crack above the Styx River in the establishment of the reservoir, lost the mana to suppress, the river is endless, rushed out of the surface, to the fourth day of the sixth lunar month, the reservoir burst, Qingcheng suffered. The water of the River Styx is still not effectively controlled, and it continues to rush out of the surface, and it is estimated that after a day and a night, the flood will extend to the five cities around Qingcheng, causing serious damage. ”

As soon as Nangong Douling heard Baojian say in detail about the good things she had done, her cheeks were hot, and Shigong said that it was a big mistake for her to kill Tianlong, but she didn't accept it at that time.

Now that she saw that the entire city was flooded, and the lives of the citizens were afraid of countless deaths and injuries, she regretted it.

"If I had known that such serious consequences would happen, I wouldn't have killed the Celestial Dragon. But no matter how much this kind of afterthought is said, it is useless, Nangong Douling lowered his head guiltily, clenched his fists, and deeply blamed himself.

The rest mage whispered, "It's not that there is no way to remedy it. ”

Nangong Douling raised her head suddenly, her eyes sparkling with excitement, she grabbed the corner of Master Anxi's clothes, "Say it quickly, is there any way to remedy it? As long as I can help, I will spare no effort! Even if it ...... Even if I take this life, I am willing!"

She's serious.

The blood is boiling and burning in her body, and in order to save Qingcheng and make up for the mistakes she made unintentionally, she would rather sacrifice herself.

The cold and indifferent eyes of the rest mage inadvertently added a layer of softness, as if to move her expression.

He said: "Just ask a new patronus and put it on the crack of the River Styx, and it will also have a suppressive effect." ”

"A new Patronus?"

"A new spirit beast will do. ”

"So suddenly, where can I find a spirit beast......" As soon as he said this, Nangong Douling slapped his head hard with his palm, "I remember, I have a spirit beast, but it's just ......"

"Just what?"

Nangong Douling said ashamedly: "I like that spirit beast very much, it is my pet, if I put it under the reservoir, wouldn't it be difficult to see it in the future?"

"Once you're in the reservoir and act as a patron saint, it's really unlikely that you will meet casually, unless you're too busy to dive and play with it every day. If you are reluctant, you can think of other ways, there are countless spirit beasts in the world, and if you spend a little time, you can always catch one to replace you. ”

Nangong Douling's heart was horizontal, "I can't waste any more time, the water will soon spread to the surrounding cities, just use my spirit beast." ”

With that, Bai Fu flew out, concentrated, and there was an extra clay pot in his hand out of thin air, wet and dripping with water, which was conjured from the home that sank under the water.

Anything can be taken out of the air, even animals, the only thing that can't be applied to humans, otherwise she would have pulled her master and uncle in front of her in the air.

Opening the clay pot, Shi Rui's toad croaked excitedly in the jar, thinking that Nangong Doubell was going to feed its grasshoppers.

Nangong Douling said: "I'm sorry, Shi Rui, there are no gnats today, and I'm afraid I won't be able to feed you in the future, so you have to rely on yourself to find food." ”
